Abstract
Dexamethasone is already routinely used as antiemetic prophylaxis for postoperativenausea and vomiting (PONV). Some evidence has been gathered in the past years forperioperative administration of dexamethasone in other indications: analgesic effects, prevention against postoperative cognitive decline or delirium, quality of recovery, prevention of complications in cardiac surgery... We performed a review of the literature to synthesize the new evidence about dexamethasone.
